OFNEW YORK, N. Y., A CORPORATION OF DELAWARE TYPEWRITI-N G MACHINE Application filed. March 9,

This invention relates to a tally-strip mechanism, which may be used in connection with a fan-foldtypewriting machine, such for in stance as the one disclosed in the patent to Nernery & Smith, N 0. 1,132,055.

In said machines a multiple-ply web is usually drawn from a supply at the rear of the machine and is interleaved with carbons to form a pack which is inserted around the platen to be typed upon. After typing a form the platen is elevated to straighten out the Web and to gage the forms to length, after which the carbons are strippedto a new form: then the platen is lowered to its normal position and the typed formsare torn off against a knife.

Sometimes it is desired to use alternately a plurality of'webs on the same machine, and it is customary to provide the machine with :l webs each having its own carbon-carrier so as to facilitate the web-changing operation. These additional carbon -carriers render unnecessary the usual rethreading of the web with carbons each time that the web is replaced. The usual condensed record-sheet for receiving the items typed on all the webs cannot be used with this type of machine, because the record-sheet usually overlies the uppermost ply of the active web and renders it difficult to replace thewebs without first with drawing the record-sheet.

It is one of the features of this invention to provide a record-sheet adapted. to alternately receive a copy of all the items entered on either web without removing the recordsheet which is at all times held in registration around the platen.

This invention can also be used to advantage for many classes of work in which a multiple-ply web is used in connection with a tally-strip, although the nature of the tallymechanism is such that the machine may be used for regular fan-fold work without the tally-strip when desired. This'feature is important as it does not impair the usefulness of the machine for regular work. In the present invention, the record or tally strip is supplied to the machine from a roll or spool which is mounted on plates carried by the platen-frame. The tally-strip is drawn down- 1927. Serial No. 173,821.

web being placed over the strip. Thewebis positioned for the first line of typingby elevating the platen and pulling the web for its normal position, the wcband the talleystrip are both line-spaced together, but since the tally-strip-receiving spool is notauto matically rotated when rotating the platen, a loop is formed between theplaten and the receiving spool. After typing a form, and prior to elevating theplaten to shift the carbons, thetally strip receiving spool is wound up by hand to takeup the slack of the strip, and the supply spool is locked against rotation so that around the platen while displacing the carbons. Sometimes, the web is provided upon the rear carriage with an extra carbon overlying the upper ply thereof, and, in this instance, the. carbon has the carbonizedside thereof contacting with the tally-strip to thereby transfer the matter typed on therweb to the tally. This extra carbon is shifted together with the other carbons. In certain classes of work, however, it is sometimes (hesiredt-o use a carbon together with the tallystrip, both being drawn together from the same supply spool and being rewound to gether on the receiving spool.

In one form of the invention the supply The tally-strip mechanism, which is attached to the platen-frame of the machine, is slanted to the rear of the machine so as to follow the usual inclination of the frontpaper-table', which facilitates reading of the wardly. Then, after the platen is lowered to the tally-strip may be held tight.

typed forms. This, of course, renders the platen top-heavy and it is difiicult to shift it to upper-case position. In order to improve this condition, there are provided a pair of side links which keep the platen straight during a shifting movement. The use of this means for guiding the platen-frame is, however, not restricted to this talley-mechanism, but it may be used to advantage to steady a platen-frame'designed to carry other heavy attachments, suchas collating tables of many kinds, stencil-cutting devices, etc.

Other features and advantages will herein after appear.

This invention is preferably applied to an Underwood continuous billing typewriting machine which has a platen 10 rotatably mounted by means of a shaft 11 on a displaceable platen-frame 12. This machine is f used'for handling a multiple-ply web 13, the

plies of which are interleaved with carbons 14 fast to a carbon-carrier 15 arranged to reciprocate on a carbon-carrier frame 16 to re position the carbons at intervals to untyped portions of the web. The assembled web is inserted at the rear of-the platen over a rear table 17, and is positioned around the platen to the printing point, in which position it is typed upon by means of type-bars 18, and line-spaced upward over front table 110 as the typing proceeds. After typing a form, the platen is elevated by swinging the platenframe on a shaft 19 cerried by a carriage 20, and after elevating the platen, the typed forms are gaged to length against the gage 21. While holding the web in this gaged position, as shown in Figure 5, the carboncarrier 15 is moved away from the platen by means of a handle 22 to thereby present the carbons to the next form.

Sometimes it is desired to use several webs in connection with the same machine, and, in order to eliminate the necessity of threading the plies of the webs with carbons prior to inserting the web in the machine, it is customary to use a carbon-carrier having two sets of carbons, one set for each web, such as is illustrated in my pending application No. 108,451, filed May 12, 1926 (now Patent No. 1,690,844, dated November 6, 1928).

In this invention it is desired to make a condensed record of all the items typed on either of two webs, as shown in Figure 7. To this end, a record-sheet 23, having an associated carbon 24, Figure 7, issupplied to the machine in the form of a spool or roll 25 which is rotatably mounted by means of a cross-shaft 26 on side plates 27 and 28. These plates form an extension of the platen-frame 12 and are displaceable therewith. The record-sheet is drawn from the supply spool 25 and is passed over a crossbar 29 and around the platen,from whichit is rewoundronto a receiving spool 30 also rotatably mounted on the plates 27 and 28 by means of a crossshaft 31. The record-sheetis always ready to receive typing thereon, and also ready to be line-spaced together with the web by means of co-operating feed-rolls 32 and 33. One advantage of this arrangement is that the displacement of the platen-frame does not disturb the position of therecord-sheet relatively to the printing line.

When line-spacing. the record-sheet together with the web around the platen, a loop is formed at the delivery side of the platen, which loop is taken up manually by winding the receiving spool which is provided with a finger-piece 34 at one end thereof. In order to prevent accidental unwinding of the receiving spool, there is provided a ratchetwheel 35 which is fast to the shaft 31 and co-operates with a retaining pawl 36 pivotally mounted on a stud 37 fast to the plate '28. This pawl is held in engagement with either manually, as shown in one form of the invention, or automatioally,.as shown in another form of the invention. The manual means for locking. said supply-spool is shown inFignre l and consists of a sliding member 39, operated by afinger-piece 40. Said member is slidably mounted on the side plate 27by means ofolips 4L0 andris moved in the pathof teeth/l1 of a ratchet-wheel e2 carried by the shaft 26, to thereby prevent rotation of: the wheel, The sliding member is normally heldinitsineftective position by means of a. spring 43, which is fast to the plate by means of rivets 44 and engages a notch 45 insaid member. This ineffective position of said member is shown in Figure 1, and the operated position thereof iss-hown in Figure 4. The sliding member is held in its operated position by the same spring 43 which engages a notch 46.

In order to understand the automatic operation of. the locking means for the supplyspool, it should be first noted that the platen? frame is heldin its normal position, as shown, for. instance, inFigure 4, by means of a locking latch 47 which. is pivotally mounted on a crossbar 4:8 and engages a locking pin 49 carried by the platen-frame. This latch is swuno' rearwardly away from the pin 49 in order that the platen may be elevated. In

.this form of the invention, advantage is taken ofthis movement of the latch 47 to simultaneously lock the supply-spool against rotation. Referring more particularly to Figure 9, in-which the latch 4L7 is shown in its normal position, it will be noted that a ton ward extension 50 of the latch 47 engages a roller 51 which in theside plate 28 and is carried by a link 53 which is operatively connected toa lockpawl 54 pivotally mounted on a pin 55 also carried by the plate 28. By means of ..d link, the latch 47 holds the pawl 54c in its ineffective position against the tension of a light spring 56, that is. a spring which is lighter than a spring 57- which operates the latch 47. Although the lockedposition of the pawl 54 is not shown in the drawings, it may be easily understood by reference to Figure 9, since it is evidentthat when the latch 47 is swung rearwardly and the roller 51 is released, the spring 56 will automatically throw the pawl 54: into engagement with the wheel 42, thereby preventing rotation thereof. This locked position will be maintained during the time that the platen is elevated and the pawl 54 will be automatically released as soon as the platen is swung back to its normal position;

In order to save carbon sometimes, espe cially when using only one web, the tallystrip issupplied to the machine without any carbon, and, in order to get a copy on the strip of the items uyped upon the-web, it is proposed to use an extra carbon 58 which overlies the web and has the carbonized side protrudes through a slot 52" thereof facing the tally-strip. This carbon is carried by the'same carbon-holder and is displaced together with the other carbons. This arrangement saves carbon, since the same sheetmay be used over and over until that the tally-strip may be easily taken oil" from; the receiving spool, the pawl 36, which normally prevents unwinding of the spool, maybe released by means of a finger-piece 63, which, by means of a stud 6 operates a camplate engaging the inner face of the pawl 36, thereby swinging it away from the ratchct-wheel 35.

The replacement of the supply spool isfacilitatcd y means of this invention. The shaft 26 is held in place on the plates 27 and 28by means of flat spring 66 which is slidably mounted on pair of studs 6'? carried by the plate 28, the heads of the studs retaining the spring. The end of the spring is slotted; at 68 to straddle the shaft 26 in a slot GSat the end thereof. In order to remove the spool, thespring 66, which is provided with a finger-piece extension 70, is moved down wardly away. from the shaft and then the shaft isbodily removed from its supporting bearings. lhesupply-spool proper, tiat is, the part which is replaced consists of a cardboard: tube 71 which is supported by means of end flanges 72 and 73. The flanges are provided with flexible jaws 74 fitting into the tube71 to thereby laterally confinethe tallystrip. The flange 72 has a hole therein for receiving a pin 75 carried bv a collar 76 fast to the shaft 26 by means of a screw 77. In order that the flange 2 may be held in continuous contact with th collar 76 to thereby rotate therewith, there is provided a spring 78, suchas-shownin Figure 2. This spring is looped at two opposite sides of the shaft 26, and bears thereagainst. The ends of this spring are fast to the flange 73 by means of screws 79, and the spring is further held in place by a stud 80 also carried by the iange 73.

The Underwood machine is provided with a platen shifting mechanism for elevating the platen to upper-case position. This mechanism is controlled by a key, not shown, which, upon depression thereof, swings a bellcrank 81 forwardly and elevates a cross-bar or rail 82, which is carried by a pair of shift-frame plates shaft 84. The platen-frameis supported on It is, of

83 pivotally mounted on a i o a e the links said rail 82 by means of a roller 85, which is carried by the platen-frame. In order that the platen-frame may be moved in a vertical plane during the shifting movement thereof, there is provided a pair of links 86 which are pivotally mounted on a cross-shaft 87 and cooperate with pins 88 fast to the platen-frame. In this invention the tally mechanism is carried by the platen-frame and both the supplyspool and the receiving spool are mounted above the platen on the plates 27 and 28 which are slightly inclined toward the rear of the machine. This renders the platen-frame topheavy and renders shifting thereof to uppercase position somewhat dificult. In order to improvethis condition, a pair of equalizing links 89 are pivotally mounted on a crossbar 90, and are designed to engage pins 91 carried by the platen-frame. Said pins 91 m 0 through a slot or seat 92 in each link in order that the platen may be swung to its displaced position, as shown in V Figure 5. Since the links 89 are mounted on brackets 93 carried by the carriage, which does not shift with the platen in this type of machine, it has been found necessary to provide a flexible connection in the form of a spring 91, so that the free ends of the links 89 may move upwardly with the platen when the same is shifted to up er-case position,

The links 89 are controlleclaterally and in their upward movement by bent ears 89 forming upon each link an integral part thereof. Said ears straddle the brackets 93,

Z 1' as shown in Figure 3.

The Underwood carriage 20 is slidably mounted on a back rail 96 and a front rail (not shown) in order that the carriage may be letter-spaced. The two rails are carried hy the frame 97. The platen-frame is dis place'able on the carriage which'remains stationary. In order that the platen-frame may be exactly repositioned after being displaced, the platen-frame is provided with locating -z lugs 98 which rest on the cross-bar 18 carried rear of the tally mechanism is provided with downwardly-extending supporting arms 100 forming an integral part of the side plates 27 and 28, which arms strike the heavy crossbar 90 mounted on the carriage.

The machine is provided with the usual line-spacing mechanism,which includes a reciprocating slide (not shown) for rotating'a I line-spacing Wheel 10 1 during the returning movement of the carriage. The line-spacing wheel is. operatively connected by means of a train of gears 102 and 103 to a gear 104 carried by the platen-shaft. V

' Referring more particularly to Figure 7 it will be noted that in addition to the regu lar carbon-carrier 15, there is provided another carbon-carrier 105, which may be of the form disclosed in my said application No. 108,451. This carrier 105 is mounted over the regular carbon-carrier 15 and is spaced therefrom by means of posts 106. The upper web, indicated by the numeral 107, is alternately used with the lower web 13, and, although either web may be operated singly, the. two carbon-carriers are simultaneously operated to strip only the carbons in the active web. The two webs may, of course, be either fanfolded or consist of distinct groups of related webs, such a group being understood as either afan-fold or a group of web-plies.

In order to facilitate the manipulation of the webs when stripping the carbons, there is provided a cross-plate 108 at the delivery side of the platen. This plate serves as a shelf for separating the tally-strip 23 from the web,

and is'secured to the side plates 27 and 28 by means of rivets 109.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
